Wireless Gamecube Controller Reviews

hey..I was just wondering if anyone has any good sites regarding this. I noticed morew and more knock offs online. My main problem with the Mad catz controller is that its too damn small.. and I would love to purchase some wavebirds, but new ones are much too expensive.
sooo..
has anyone had experiences with any third party wireless game cube controllers? Good or bad? With the advent of super smash upon us I think we need to collaborate and make up a guide of wireless controllers we should buy or those we should stay away from...

Seems to be a bit small as well..but it works well..
I am also concerned of the action button placement notice that it is similar to the classic controller of the WII but different than that of the gamecube controller.

IE) in the game cube version, the X and Y are in the upper right while the b is on the left, while the A button would be on the bottom.
